I want to use a buffer analysis to identify the geodemographics of Incinerators. I have downloaded the Output Area Classification (OAC) map and also know the locations of all the Incinerators I want to analyse from an online map. I want to know how i can perform a buffer analysis from the geographical point in which the Incinerators are located based on the OAC map.

Forgive me if I'm missing something, but it seems that all you need here is your point shapefile and the buffer tool which is located at: Analysis Tools -> Proximity -> Buffer
Specify your input points and a buffer distance. Use the "Show Help" pane in the tool if you need guidance on some of the tool options.

2Yes, you'll need to create a shapefile of these locations. You can create the shapefile from a spreadsheet that has your x,y coordinates using ArcCatalog. Browse to the folder where the spreadsheet resides and right-click and choose from the options that appear to create a shapefile. Commented Jul 11, 2011 at 15:17
You can also open these in python as points and simply loop through them, buffering each one. It's a very simple bit of code to do them all.
